This invention relates toliquid disp'ens-' ing systems andhas referencemore particularl to improvements in apparatus for use in dispensinggasoline. r

In dispensing gasoline, it is customary to first pump the gasoline intoan elevated glass container graduated in gallons. From this elevatedcontainer the gasoline-is run by gravity. into the fuel tanks of theautomobiles. I

In Patent- No. 1,466,273, granted to me n August- 28, 1923, .I havedescribed and claimed aliquid dispensingapparatus that is adapted foruse where the gasoline-is transferred. from the underground storage tankinto the glass dispensing container, by means of a pum as distinguishedfrom installation .where the gasoline.

sure. In installations of this type it is often desirable to'locate thestorage tank at some distance from' the dispensing apparatus which makesit desirable that only a single 'fied, I have shown an apparatus inwhich pipe shall he -needed to connect the tank with the" dispenser, Inthe patent, above identionly a single pipe is used'to connect thestorage tank with the. condenser.

It is the objectof this invention to modify the'constructlonshown anddescribed in my above referred to patent so as to simplify the same andso @s to make it possib e to place the overflow or float tank underround, instead of within the casing of the ispens- This makes itpossible to.

draw the thspensin container into the float tank at nightand'm otherways simplifies the construction. I

. The above and other objects which'will appear as the descriptionproceeds, are attained by means ofa construction and arran mentthatI-will now proceed to dein detail, reference for this purpose 'bein hadto the accompanying 1n whic my invention is illustrated an which thesingle figure shows a vertical sec-' tion through a liquid dispensingapparatus constructed in accordancewith my present invention.

In the drawing numeral 1 designates a rent glasscohtainer that isgraduated in gallons and fractions thereof. This bowl is clamped between;the-'base mernber 2 and top 3 by means of a central for hard. The dispebowl assembly rest's'upon the top of the conical casing 5. A.";j8u0t1011 or .tank 17. is a float ope fill line 6 extends from the basebracket 7 7.to a point near. the top of the dispensing container whereit termlnates a short distance below the upper .end of the fill pipe. Adrain pipe 10 connects the strainer 11 with the delivery p; dispensinghose 12. A valve 13 serves to ntrol the escape of theliquid through thepipe 10. A by-pass indicated as a whole by-numeral 14 connects the drainpipe 10 with the overflow pipe 9. This byp'ass iscontrolled' by astop-cock l5'which may be opened at n ht or whenever it becomesnecessary or esirable to drain the container 1. Unless some s ecialconstruction, such as that describe in the above identified patent isresorted to, it becomes necessary to extend the overflow pipe 9 to thestorage tank 16 which frequently in-- pared to the capacit 7 of the tank16, but

which must be slight y larger than the container 1 so that it will bepossible to drain the latter atany time. The suction orfill .line 6, inthe preferred construction, extends through the tank 17, in the mannershown, and passes from thence tothe inside of the storage tank 16 nearthe bottom of which it terminates in'a-foot valve 18. Within the ratedvalve having a body portion 19 which is provided with an opening whichis controlled by a movable valve member 20 that is connected to thefloat controlled lever 21 by means of a link 22. When the tank 17 isempt the valve is closed but "when liquid enters t e tank 17insuflicient quantity toraise the float 23, the valve member 20. is movedto open position,

wardly and into the dispensing container in a manner perfectly-obviousfrom an in spectionof the drawing. The. overflow pipe 9 enters the tank17 in the manner shown.

It is now evident that any; overflow that may.

occur while filling the container 1, as well as the contents ofJthelatter when the stopcock 15 is opened, will flow into the tank 1 I haveshown the tank 17 provided with a vent pipe 17 that extends upwardly andopens into the top of the measuringbowl.

.This permits the air to escape from the tank to the bowl when thelatteris drained. The storage tank 16 is filled through the pipe 24 and isvented through ipe 25. In order that the pump 8 may he primed, if th1sshould become necessary, I have attached to the pipe 6, ate. pointdirectly above the pump, a priming pipe 26 controlled by a valve 27.

Let us now assume that the parts are assembled in the manner shown andthat the pump is operated. Gasoline will be transferred from the storagetank to the graduated container 1. When the level of the gasoline in thecontainer 1 reaches the top of the overflow pipe 9, it will overflowthrough this pipe and pass into the tank 17. As soon as this occurs thepump should be stopped. No harm, however, will be done if the pumping iscontinued for as soon as the float 23 opens the valve, the pump, insteadof raising gasoline from the storage tank, will merely return thegasoline from the overflow tank to the container 1. This circulation maybe continued as'long as desired. At night or at any other time, when itis necessary or advisable to drain the container 1', the stopcock 15 maybe opened. This permits the 'gasoline to pass down and into the tank 17where it. will remain owing to the fact that the foot valve 18 preventsit from returning to the storage tank 16. The float 23 will, however,open valve 19 and when the pump is operated the liquid in tank 17 willbe the first to be returned to the container.

As soon as the valve 19 closes, liquid will beraised from the storagetank. I have shown the fill line 6 as passing throughthe tank 17, butthis is not absolutely essential, although desirable for structuralreasons. It is evident, however, that the pipe 6 may merely have abranch extending into the tank 17 and controlled by a valvelike the onedescribed.

The main point of distinction between m prior invention, above referredto, and tlns one is that in this construction the overflow pipeopensdirectlyinto the tank 17 andthe latter is large enough to permitthe entire contents of the container 1 to be drained into it; This makesit possible to use a foot valve in the lower end of the fill pipe whichcannot be done where the .float tank is smaller than the container 1.With my present construction the tank 17 maybe placed underground whichminimizes the fire risk. In the patent above referred to, there is nofoot valvecorresponding to the valve 18 as this would prevent theoverflow from returning to the, storage'tank. The tank 17 is shownbroken away and has any capacity at least slightly greater in volumethan the transparent container 1.

Having now described my invention, what I claim as new is: 1

An apparatus for dispensing liquid in measured quantities, comprising,in combination, a storage tank adapted to be placed under ground, ameasuring bowl adapted to be supported. in elevated position above thestorage tank, a suction pipe connecting the storage tank and themeasuring bowl, a

pumpin said suction pipe, for transferring liquid from the storage tankto the measuring bowl, an overflow pipe extending downwardly from apoint within the measuring bowl, an overflow tank between themeasuropening and a check valve in the suction pipe between the overflowtank and the storage tank, said overflow tank having a capacity at leastas great as the maximum capacity of the measuring bowl, whereby theentire contents of the'latter may be transferred to the overflow tankand a vent pipe connected at its lower end with the overflow 1 tank andhaving its upper end opening at a point above the maximum liquid levelof the measuring bowl.

In testimony whereof I afl'ix my signature. EMORY OROUSE.
